Done right, nitrous will be more than a turbo upgrade, and a turbo has a 50K mile+ life span. The turbo keeps giving, and the nitrous bottle keeps giving out.

Have to dispute this. With nitrous, the extra combustible air is instantly available, when you have the bottle filled, and the temperature/pressure is right, and everything is activated, and your timing is reduced, fittings are tight and not leaking, you have the correct failsafes in place so that your IM doesn't end up in your hood scoop, etc.

With a turbo, I can start up the car, get it warm, and there is the power.

Adding a turbo kit to a non-turbo car, vs. adding nitrous, different ballgame, but with the OEM management and failsafes in place, I don't see the reason unless, like stated earlier, you need the spool, you need the money, or you want it.
